Carbon Isotope Constraints on the Deglacial CO 2 Rise from Ice Cores
By the Numbers As carbon dioxide is exchanged between the atmosphere, the oceans, and the terrestrial biosphere, its carbon isotopic composition is modified by various processes involved in its transfer between the different reservoirs. The carbon isotopic composition of the carbon dioxide contained...
